Reviews of the small number of products that I recommend everybody should have you will find at Recommended Resources.

Here you will find products that have special or limited application depending on your particular requirements.

Traffic Equalizer

This is a "directory builder". It uses search engine results to construct topical links pages. Definately modify the templates and look at working on the linking structure a bit by adding the nofollow tag in all the right places. The right places you say? See Mastering PageRank of course!

I have used this product on a number of domains and it appears to work well.

LMA

This is "free" tool with the understanding that you do not modify the code and do not remove the (very small) advertising links that the author has sold to support the development. LMA will also automate the reciprocal linking process including checking that your return link is in place and sending emails for various conditions.

I have only started to experiment with this tool, so I might need to update this review later, but for now it appears to work pretty well.

RSS Equalizer

I used this on one test domain just to try it out. It works as advertised. The issue is how to apply it. I would recommend that RSS be used to "fatten" pages rather than build the entire content of a page. Using this tool with TE could make sense. This still creates a page with no content you have actually had to create, but the variety of sources makes it look a bit less artificial.

Article Equalizer

I have not yet tried this product, but the concept has been done before and has worked well. Given that Jeff has executed well on the other *Equalizer programs, I expect that this will work as well.
